SPRAYvING .DEVICE FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 745,178, dated November 24, 19-03.

Application filed July 24, 1903. Serial No. 166,903. (No model.)

To a/ZZ whom it may concern:

Be it known that I, GRIGORY GORDEJEFF, a subject of the Czar of Russia, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in Spraying Devices for Liquids; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to spraying devices that class of such devices by which the liquids-for instance, liquid fuel-#are sprayed by purely mechanical means and not by means of steam or gas or of air under pressure.

The object of myrinvention is to produce a spraying device of the said type which being simple, cheap, and durable secures at same time a very perfect Spraying of a liquid .supplied to the device under pressure.

To this end my invention consists in the construction and combination of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure l is a front elevation, partly in section, of my improved Spraying device. Fig. 2 is a plan of that of the two parts of the casing of my device which carries the spraying-piece. Figs. 3 and 4 are respectively a top view and a front elevation, partly in section, of this piece, shown on a larger scale.

My device has a casing formed of two parts l and 3, the latter having the shape of a cap screwed on the end of the former. The part l is provided with a branch 2 for the liquidsupply pipe and carries the means by which the inlet for the liquid is controlled, whereas in the removable cap 3 the piece producing the pulverizing or spraying of the liquid is inserted.

The inlet for the liquid is provided in a partition 4i of the casing l and controlled by the pointed end of a screw-threaded spindle or rod 6 in a well-known manner. The cap 3 has a central discharge-orifice 7 at the-point of a short conical recess 7', made from the inner Side of the front Wall (or bottom) of the cap. This cap is interiorly screw-threaded to correspond with the threads `on the end of the casing l and on the disk 9 of the spindle S, two parallel flat sides 14, Fig. 2, being provided on the cylindrical cap to facilitate a tight assemblage of the same with the casing l.' The spindle or rod 8, fitted at the middle with the said screw-threaded disk 9, Figs. 3 and ai, has one end l5 enlarged and the other provided with two parallel dat sides I3. In the front surface of the enlarged or head end of the spindle 8 are formed eccentrically-arranged grooves or channels l2, Fig. 3, leading from the periphery Vof the spindle to the periphery of a centralrecess ll ,Whichis preferably conical in shape. When the piece S 9 is Wholly screwed in in the cap 3, the enlarged end l5 of the spindle 8 fits tightly the bottom of the cap and overlaps the discharge-openin g 7. The recesses ll and 7 form then a cavity in the shape of a double cone which is in communication with the outer air by the'discharge-oriiice 7 and with the interior of the cap 3 through the said eccentrically-arranged grooves l2. The disk 9 of the spindle of course is provided with channels or ducts for the liquid to be sprayed. Thevsame may have preferably the shape of narrow radial slots l0, as clearly shown in Figs. 3 and 4:. The spindle 8 is made of such a length that the flattened end 13 will also project above the cap when the piece 8 9 occupies the working position, Fig. l, within the said cap.

The operation of my spraying devices is as follows: The liquid, which may be previously heated and filtered, enters through the branch 2 and the small channel 5, controlled by the plug 6, passes then through the slots l or other passages in the disk 9 to the grooves 12 in the head end l of the spindle 8, which grooves being arranged eccentrically lead the liquid into the cavity formed by the two aforesaid recesses 11 and 7', so as to cause it to rapidly revolve within this cavity and to be projected through the discharge-aperture 7 under the same condition of motion, affording in that Waythe perfect spraying of the liquid bythe impulsive force of the pressure under which the liquid is admitted and the centrifugal action.

If in the disk 9 are provided narrow slots l0 instead of round passages or the like, the liquid is here subjected to an additional filtration-viz., solid foreign matters Will be retained and therefore cannot stop up the discharge-openin g 7 or the small channels l2.

Having noW described my invention, What I claim isl. A spraying device comprising a casing having a converging aperture and a spindle provided with a diverging recess adapted to register with said aperture and having passagesleading from the recess to the periphery, substantially as and for the purpose specified.

2. A spraying device comprising a casing having a converging discharge-aperture, a spindle provided With a diverging recess adapted to register with said aperture and having eccentricall f' arranged grooves or channels leading from the periphery of the spindle to the periphery of the recess, subl stantially as and for the purpose specified.

3. A spraying device comprising a casing having a converging aperture, a spindle provided With a diverging recess registering with the aperture and having eccentrically arranged grooves or channels leading from the periphery of the spindle to the periphery of the recess, and a disk on said spindle having passages formed therein, substantially as and for the purpose specified.

1i. A spraying device comprising a casing having a convergingaperture, a spindle having a diverging recess registering with the aperture and having eccentrically-arranged grooves or channels leading from the periphery of the spindle to the periphery of the recess, and a screw-threaded disk on said spindle having radial slots formed therein parallel to the axis of the spindle, substantially as and for the purpose specified.

5. rlhe combination With a casing having a discharge-nozzle, of a spindle having a cen tral recess therein, and means to supply liquid tangentially to the recess and in a plane at right angles to the axis of the spindle, substantially as described.

6. In spraying devices for liquids admitted under pressure the combination with a cap having a central discharge-opening at the point of a conical recess, of a spindle provided on its front surface overlapping the said conical recess, With a central recess and with eccentrically-arranged grooves leading' from this recess to the periphery.

7. In spraying devices for liquids admitted under pressure, the combination With a casing and a cylindrical cap screwed on the end of the said casing and having in its bottom a central oriiice at the point of a conical recess, of a spindle, a screw-threaded disk, having passages for the liquid, on the said spindle, a central recess on its enlarged end and eccentrically arranged grooves or channels leading from the periphery of the spindle to the periphery of the said central recess.

8. In spraying devices for liquids admitted under pressure, in combination a casing, a cap With a central discharge-orifice at the point of a conical recess a spindle screwed in said cap so as to overlap by its front the said discharge-opening, a central recess in the said front, grooves leading from the periphery of the said recess to the periphery of the spindle, a screwthreaded disk on said spindle and narrovi radial slots in the said disk.

In testimony that I claim the foregoing as my invention I have signed my naine in presence of tWo subscribing Witnesses.
